Principle of Siemens inverter Parameter setting of Siemens inverter

Siemens inverter is an electric device that can change the running frequency and voltage of the motor, also known as "speed regulator" or "variable frequency speed regulator". It can control the voltage and frequency of the AC power supply equipment and provide the output signal to the motor so that the motor runs at the preset speed. Siemens inverter has good control performance, high precision, high reliability, energy saving and other characteristics, and is widely used in industrial automation, machine tools, metallurgy, machinery, energy, building materials, petrochemical and other fields.

The parameter setting of Siemens inverter involves many aspects. The following are some key parameter settings:

1. Rated current and power: First, you need to set the rated current and power of the inverter according to the rated current and power of the motor.

2. Frequency control mode: The common frequency control modes of Siemens inverters include basic frequency control, vector control and direct torque control. The corresponding frequency control mode needs to be selected according to the actual application.

3. Acceleration time and deceleration time: Acceleration time and deceleration time refer to the time required for the motor speed to reach the target speed from the starting speed. It needs to be set according to the actual application to ensure system stability and efficiency.

4. PID parameters: If closed-loop control is required, PID parameters need to be set, including proportional coefficient, integral coefficient and differential coefficient.

5. Output frequency range: The output frequency range of the inverter needs to be set to ensure that the output frequency is within the range that the motor can withstand.

6. Overload protection: Set the overload protection parameters to ensure that the system can be shut down in time for protection when the load suddenly increases.

The above are several key parameters for Siemens inverter parameter settings. The specific parameter settings need to be carried out according to the actual application situation and user manual.

Siemens inverters were first used in the Chinese market in the steel industry. At that time, motor speed regulation was mainly DC speed regulation, and the application of inverters was still an emerging market. However, with the continuous development of electronic components and the continuous maturity of control theory, frequency conversion speed regulation has gradually replaced DC speed regulation and become the mainstream of drive products. Siemens inverters have achieved super-scale development in this huge Chinese market due to their strong brand effect. The successful development of Siemens in the Chinese inverter market can be said to be a perfect combination of Siemens brand and technology.
